WRAPPING-MACHINE.

Specification of Letters Patent.

Application filed December 22, 1909.

To all whom it may concern:

Be it known that I, VV1 LIAM P. SARGENT,

a citizen of the United States, residing at Philadelphia, in the countyof Philadelphia and State of Pennsylvania, have invented a certain newand useful rapping-Machine, of which the following is a specification.

Objects of the present invention are to provide a machine which willmake high grade rolled packages more rapidly and better than can be madeby hand, even by the most expert operators, and such as are requlred fordistributlng the very best publlcatlons to the readers in as goodcondition as 1 they are when they leave the binder, even though thepublications represent the highest degree of excellence in thetypographical and illustrative arts; and to provide a machine by whichsavings are efiected in ref spect to time and labor, to wrappingmaterial, and to the bulk of the packages.

Other objects of the invention will appear from the followingdescription of the invention which is made in connection with one, butnot the only, embodiment of it chosen for illustration.

In the drawings, Figure 1, is a side view of the machine. Fig. 2, is atop or plan view of the parts shown at the right hand side of Fig. 1.Fig. 3, is a view of the side of the machine opposite to that shown inFig. 1. Fig. 4, is a View principally in section of the machine, andFigs. 5, 6, 7, 8, 9,

and 10, are views illustrating the operation of the machine.

In the drawings 1 and 2, are side frames which carry the various shaftsand journals, which will be presently described, and which are shown asmounted upon legs or supports 3.

4, is a belt shown as of the endless variety and positively driven bymeans which will be described. In the drawings it is shown to consist ofthree parts, but I do not intend a pair of feed rolls 5 and 6 aroundone, 6, of which the belt passes, an idle roll 7 shown as a freelyrevoluble sleeve, an idle roll 8, a belt tightener wheel 9, a drivenroll 10, a pinch roll 11, and a guide 12, shown to consist of a bar.These parts, with the exception of the members 6, 11 and 9, are arrangedbetween and suitably supported by the side frames 1 and 2 The rolls 6and 11 are journaled in arms 13, pivoted on the shaft 14, or in otherwords, are mounted in a swinging frame. The belt tightener 15, of whichthe pulley 9 is a part, is adjustably connected with the springs 16.Inasmuch as there are several belt tighteners they are adjustablyconnected with a bar 17, to which two springs 16 are connected. The downward movement of the bar 17 is limited by adjustable stops 18 carried bybrackets 19.

Power is applied to the machine as by means of the pulley 20, which bythe beveled gearing 21, drives a shaft 22 arranged with in the sleeve 7and extending across the machine. At the other end of the shaft 22 thereis a sprocket drive 23 (Fig. 3) to the shaft 14. At the other end of theshaft 14 (Fig. 1) there is a train of gears 24 carried by one of thearms 13 and connected with the feed roll 6. Referring to Fig. 1, thecross belt 25 driven from the shaft 22, drives the roll 10. The runningloop or bight produced by the described means is indicated at X. Thestop 18 is obviously instrumental in forming this loop or bight. Theloop is produced by a slackness in the belt and it may be said that itis empty in the sense that there is no mandrel, guide or equivalentfound in it. The loop is maintained by directing the slackness to anappropriate position. The loop is on the slack side of the belt which isthat part of the belt that has passed the driving roll 6. The drivingroll 6 and an appropriate guide, of which 12 is an example, are meansfor maintaining and producing the loop.

Inasmuch as the feed roll 5 sometimes contacts with the belt, as will behereinafter described, the means for driving it will now be described.

Referring to Fig. 3, the cross-belt 26 driven. from the shaft 14 drivesthe roll. 5.

The belt tightener is a means for permitting spiral formed by thepublications within the loop or bight X and to control the size of therolled package. There are devices for opening the bight or loop X topermit of the removal of the wrapped publication and these devices willnow be described. These devices include the provision of means by whichthe feed rolls 5 and 6 may be supported, and more specifically theswinging arms 13 and their operating mechanism.

27, is a cam driven from the shaft 22 (Fig. 1) by gearing 28 on one endof the shaft 29. At the other end of the shaft 29 (Fig. 1) there is asprocket wheel which through a chain 30 drives a sprocket wheel 31 fastwith the cam. Thecam shown is of the edge variety and operates upon apivotal arm 32, connected by means of a link 33 to an arm 34 of a rockshaft 35 having a pair of arms 36 arranged on each side of the machineand respectively connected by links 37 with the swinging arms 13. Thecam 27, not only operates to open the loop, but also changes therelative positions of the feed rolls for purposes which will behereinafter described.

38 is a conveyer belt arranged between the side frames of the machineand as shown its roller 39 is driven by the belt 40 from the shaft 22.

41 are lifting or deflecting belts and are arranged between the parts ofthe belt 4, and they pass around the roller 6 and around the roller 42carried by arms 43 freely pivoted to the shaft 14 and acted upon bytension springs 44. 45 are adjustable back stops forthese arms and theseback stops are carried by the arms 13.

46 are adjustable tension springs connected with the arms 13 and withthe frame of the machine. These springs 46 serve to adjust the pressurebetween the feed rolls 5 and 6.

47, are deflectors, shown as attached to the bar 12 and arrangedintermediate of the parts of the belt 4, and they serve to positivelydeflect the advancing edge of the publication to start the formation ofa spiral. The deflectors 47 are fixed and project into the loop X andare effective crosswise of the direction of the outgoing portion of thebelt constituting the loop. In the construction shown in Fig. 7, theoutgoing portion of the loop is to the right of the reference letter 00and the portion of the deflector that ranges or depends across thisdirection operates on the edge of the magazine to start the spiral rollas can be understood from Fig. 5.

The operation of the machine in the production of a roll may bedescribed as follows: Referring to Fig. 7 the flexible publication a,with the wrapper 6, either following or partially underlying it, is fedon the conveyer 38. In this position the rolls 5 and 6 are in contactwith the belt and pressed toward each other and the loop or bight Xis'formed and the swinging frame, which is made up of the arms 13, is inhigh position and consequently the cam roller of the arm 32 is on a lowpart of the cam. As shown in Fig. 8, the feed rollers are separated forthe admission of the publication to the loop X. Under thesecircumstances the cam roller of the arm 32 is on a slight rise 48 of thecam. At the next step the roller on the arm 32 is free from theprojection 48 and the feed rolls 5 and 6 bear upon the publication andfeed it into the loop. This feeding continues until the origin of thespiral is formed. This is shown in Fig. 5 and it will be noted that thedeflectors 47 play a part in forming the inner convolution of thespiral. The belts 41, when present, assist in this operation by liftingthe advancing edge of the magazine into line with the loop X. Inasmuchas the sheets of the publication are bound along one edge, it followsthat as the spiral is formed the sheets should be free to sliderelatively to one another. For this purpose the feed rolls 5 and 6 areslightly separated. A slight rise 49 on the cam 27 actuates the arm 32which in its turn properly positions the swinging frame for thispurpose. The last described positioning of the feed rolls 5 and 6 inrespect to each other not only accomplishes the purpose recited, butalso permits the wrapper to enter the bight or loop X without wrinklingand also keeps the feed rolls clear of its pasted portion. This isindicated in Fig. 9. As soon as the feeding action of the rolls 5 and 6is-terminated, as has been described, the rolling action is performedentirely by the belt 4. As shown in Fig. 6, the publication remains inthe loop or bight X sufficiently for fixing the paste or agglutinant. Asshown in Fig. 10, the running loop or bight X is open freeing thewrapped publication for removal. The opening of the loop or bight isaccomplished by the action of the part 50 of the cam, which shifts theswinging frame 13 to its lowest position. Evidently when the part 50 ofthe cam clears the arm 32 the swinging frame is returned to its initialposition and the belt 4 contacting with the driven rolls 5 and 6 iscaused to re-form into the loop or running bight X.
